Suri Cruise may be a budding fashionista, but Gwen Stefani and Gavin Rossdale's son Kingston is clearly the most stylish boy in Hollywood.

In fact, the tot -- who celebrates his fifth birthday on Thursday -- has been known to emulate his parents' rocker looks, which include everything from leather jackets to fringe boots and destroyed denim jeans.

Stefani, 41, admits that it hasn't always easy raising such a fashion-forward son. "Kingston's whole thing is, 'I need, I need.' He is insane right now," she told ELLE in July 2009. "We're just hoping for the best and that he's not going to turn out to be a freak, but we'll see."
